wpf 应用程序似乎阻止了 HP 笔记本电脑上的扩展屏幕功能
我遇到了一个奇怪的问题,一旦我运行 wpf 应用程序,我的 hp 笔记本电脑上用于扩展屏幕的“fn_key -- F4”组合将停止工作。即使我创建一个空应用程序,也会发生这种情况 - 一旦运行它,我就无法将桌面扩展到第二个显示器。
谢谢!
I ran into a strange issue where "fn_key -- F4" combination on my hp laptop to extend the screen would stop working once I have a wpf application running. This happens even when I create an empty app -- as soon as I run it, I can't extend my desktop to a second monitor.
Thanks!

听起来像是您的视频驱动程序的问题。它是什么类型的视频卡?您是否正在运行供应商提供的最新驱动程序?
Sounds like an issue with your video driver. What kind of video card is it? Are you running the latest drivers from the vendor?
问题是驱动程序问题(正如德鲁上面提到的)。
